   1. (if you cant play this click the yellow bar at the top of your screen and allow it)
2. Matter can combine physically and chemically. You need to know what examples of matter mixing involve chemical reactions and physical ones. Copy and paste the list and table below to your webpage. Then cut and paste the phrases into the table on a wiki on your website titled 7-3 Classification of Matter. P.S. all the rows under chemical changes will be full when you are done.
